Hva betyr feilkoden?
The engine control module (ECM) receives too low a signal from the position sensor that controls the turbo's variable guide vanes. The position sensor tells the module where the vanes are. Without a valid signal, the module uses a fixed value for the turbo position instead.
Mulige årsaker
- Loose connections
- Contact resistance or oxidation in the connections
- Signal wire shorted to ground
- Moisture in the air intake system
- Damaged position sensor
- Open circuit on the signal wire
Hva du kan gjøre
- 1Check that the connector to the turbo position sensor is firmly seated and free from oxidation
- 2Check the sensor wiring for chafing and breaks, and with a multimeter that it is not shorted to ground
- 3Check the air intake system for moisture or water
- 4If you have a diagnostic tool: read the position sensor value in live data and see whether it changes as the engine revs up
- 5Erase the code and test drive; if it returns after checking the connector, wiring and air intake, have a workshop check the position sensor
Symptomer du kan merke2
- Check engine light comes on or behaves abnormally
- The car feels sluggish or lacks power
Hva feilen kan påvirke2
- Exhaust gas recirculation (EGR) control stops
- The engine control module uses a fixed value for the turbo position
